Cotahuasi has is widely accepted as the worlds deepest canyon. Reaching a depth of around 3535m (although sources often differ widely), it dominates the surrounding landscape. Isolation adds to its drama; wonderfully elaborate cacti thrive in the arid climate, sheer cliffs rise abruptly from thunderous rivers, and hanging bridges over the canyon provide a daunting path.
The best base from which to explore Cotahuasi is Arequipa, known as La Ciudad Blanca after its grand colonial buildings of white volcanic rock. Now a UNESCO World Heritage Site, the centre has some stunning architecture, and within Peru is considered second in beauty only to Cusco. Make sure you keep in mind, however, that at an altitude of 2,380m, this area will require some acclimatization.
Culture and customs in this area are fascinating. The relative isolation has sheltered many traditions which have disappeared elsewhere, and the strongest influences have come from the Peruvian highlands, rather than from the more developed city of Arequipa. As with the more famous Colca canyon nearby, evidence of the Inca empire and of older cultures is strong around Cotahuasi, with ancient trails, agricultural terraces and Wari tombs.
There are several good shorter treks; near the deepest part of the canyon, one follows a 1200 year old Inca trail down its side to the Marpa valley, rich with ancient ruins, and it is only a 7-8 hour round walk from Cotahuasi town to the stunning Cataratas de Sipia. However, difficultly in access makes a guided hike worthwhile. Peru Adventure Tours offer a six day trek which looks particularly good, and covers the canyon's attractions comprehensively.

Best times to walk/weather
Best times to walk
Between June and September.
The rainy season lasts throughout January, February and March, whilst temperatures do not alter much over the year. In Arequipa, daily minimums go down slightly from April to November/December, but tend to stay between around 5.5 and 8.8°C. Maximums vary between 21°C and 22°C, no huge difference. However, the ecosystem of the canyon means that temperatures can vary hugely in the area, whatever the season.For detailed weather information, have a look at: www.worldweather.org or www.bbc.co.uk/weather/world/country-guides
Getting there/transport/permitsThose on organised expeditions will generally be transported from/to Arequipa.
Arequipa is reasonably easy to reach from the larger cities in Peru, with short domestic flights from Lima, Cusco, Tacna or Juliaca. Trains are available from Cusco, Juliaca or Puno, and buses run regularly from Lima and Tacna as well as from cities in Chile and Argentina. However, public transport is not necessarily quick or reliable in South America, so plan carefully.The village of Cotahuasi provides a good base from which to walk the canyon independently, but is very isolated – you will probably need to drive if you have not arranged trekking with a guide.No permits are needed to do this walk.
Route(s)There are various routes for walking in the canyon (see Walk Summary above) – think carefully about which is most likely to suit you.Interactive map

Guided or independent?
You can explore the Cotahuasi Canyon independently, but the inaccessibility of much of it means that a guided walk is recommended, with people to drive you when necessary.
Guided/supportedWhile Cotahuasi can be explored, and some walking undertaken, independently, most people wanting to do any prolonged hiking here form or join organised/supported expeditions. Given the inaccessibility of much of the canyon and difficulty of getting supplies, many will prefer to do it this way, and travelling here with a knowledgeable guide has real advantages. Expedition organisers include:
AccommodationCamping is the only realistic option for the majority of a long hike in the Cotahuasi Canyon. There are hotels and lodges in Arequipa, in the town of Cotahuasi and in several other small places, but they tend to be fairly basic.Hostelbookers usually has a good selection of cheaper-end accommodation.
